Abstract: 【Objective】To measure Chinese agricultural carbon emissions and carbon emission intensity,explore the time variation characteristics,analyze the driving factors of agricultural carbon emissions,in order to provide theoretical basis for achieving green,low-carbon and high-quality agricultural development.【Methods】Based on relevant data on agriculture and energy in 29 provinces（autonomous regions and centrally administered municipalities） from 2000 to 2020,combined with IPCC classical carbon emission measurement method,carbon emission measurement system was built around three aspects：agricultural land use,agricultural inputs and livestock and poultry breeding. The driving factors of agricultural carbon emissions were analyzed using the LMDI model.【Results】From 2000 to 2020,Chinese agricultural carbon emissions increased from 27.790 0 million t to 29.409 6 million t,while the agricultural carbon emission intensities decreased from 1.329 t/ten thousand yuan to 0.618 t/ten thousand yuan. From regional perspective,central and eastern were the main regions of Chinese agricultural carbon emissions. The contribution values of agricultural industrial structure,agricultural labor force size and agricultural energy structure to agricultural carbon emissions were -24.284 3 million t,-12.048 6 million t and -10.240 5 million t respectively. While the contribution values of agricultural energy efficiency and agricultural economic level were 37.865 7 million t and 10.327 3 million t respectively.【Conclusion】Chinese agricultural carbon emissions as a whole showed a trend of “rise-fluctuation rise-fluctuation drop”. The total and intensity of agricultural carbon emissions in regions with high levels of economic development had high reduction rate. The main regions of agricultural carbon emissions were concentrated in the central and eastern regions. Agricultural industrial structure,agricultural labor force size,and the agricultural energy structure played positive roles in achieving agricultural carbon emission reduction,while agricultural energy efficiency and agricultural economic level promoted agricultural carbon emissions to a certain extent.
